Sony's taken some strong steps against PS3 cracking in the past week -- not only has it taken to the courts and won a temporary restraining order against Geohot and fail0verflow for cracking the console, but it also released firmware 3.56, which locked things down again. Unfortunately, that restraining order doesn't mean anyone else has to stop a-crackin', and wouldn't you know it: 3.56 was cracked open in less than a day by KaKaRoToKS, who was behind one of the first 3.55 custom firmwares. Now that the 3.56 signing keys are out, we'd guess updated custom firmware is soon to come -- and we'd bet Sony's lawsuit will just inspire an entirely new wave of people to jailbreak once those hit the scene. Way to put that genie back in the bottle, Sony.

Update: We're hearing that new custom firmware isn't on the table quite yet, because Sony changed most of the locks, and is reportedly actually storing the all-important ECDSA private key with random-number cryptography this time around. Be warned: if you upgrade to 3.56, there's no easy way back down. In related news, Github complied with a DMCA takedown notice to remove KaKaRoToKS's repositories, so you'll have to head on over to Gitorious (at our more coverage link) to get at the fail0verflow tools.
